A luxury bathroom is a personal sanctuary, and the right trims create a waterproof, elegant atmosphere. PU is the right material for luxury bathroom trims because it handles the humidity and the splashes without damage, and the material can be produced in any profile, size, or finish.
The most common luxury bathroom trim is a substantial cornice. A developed cornice, 80 to 150 millimeters of drop, in a restrained classical or transitional profile. The cornice frames the ceiling, and the design supports the room's elegant atmosphere. The finish is a moisture-resistant enamel that's easy to wipe clean.
A second common luxury bathroom trim is a substantial baseboard. A tall baseboard, 120 to 180 millimeters, in a developed classical or transitional profile. The baseboard grounds the wall, and the design supports the room's elegant atmosphere. The finish is a moisture-resistant enamel.
A third common luxury bathroom trim is a panel molding on the main wall. A panel grid on the wall behind the vanity or the tub, with a developed classical profile. The paneling is the focal point of the room, and the design supports the room's elegant atmosphere.
A fourth common luxury bathroom trim is a ceiling medallion. A medallion above the main light fixture. The medallion is a focal point in the room, and the design adds an architectural element to the ceiling.
For sourcing luxury bathroom trims, the right conversation with the factory is about the room's design, the moisture exposure, and the durability requirements. The factory can advise on the right profiles, the right finishes, and the right fire rating (if required) for the specific bathroom.
A practical note on the waterproofing. Luxury bathroom trims are waterproof, but the joints need to be sealed with a waterproof caulk (silicone or polyurethane) to prevent water from getting behind the trim. The caulk should be a kitchen-and-bath formulation with mildewcide, and the caulk should be inspected annually and replaced if needed.
A practical note on the ventilation. Luxury bathrooms should be properly ventilated to reduce the humidity level. An exhaust fan that runs during and after showers is the standard solution, and the fan should be sized to the bathroom's volume.

Frequently Asked Questions
Q: What is polyurethane (PU) decorative material?
A: Polyurethane (PU) decorative material is a high-density closed-cell polymer molded into architectural profiles such as cornices, ceiling medallions, wall panels, columns, and skirting boards. It replicates the appearance of plaster, carved wood, or stone at one-quarter the weight, is fully waterproof, impact-resistant, and arrives factory-primed for paint.
Q: How does PU compare with plaster and wood mouldings?
A: PU is lighter than plaster (no scaffolding required), impact-resistant during transport, and immune to cracking. Compared with wood, PU does not warp, split, or attract termites, and it tolerates moisture in bathrooms and kitchens. The trade-off: PU cannot be refinished the way solid wood can, but its lifespan is 20–30+ years with minimal maintenance.
Q: How do you cut and finish PU mouldings?
A: Cut PU mouldings with a fine-tooth miter saw (40+ teeth for a 10-inch blade) to avoid chipping the molded edge. Sand the cut edge with 220-grit, then apply two coats of interior latex paint. Mitre joints at corners, fill seams with lightweight spackle, sand smooth, and finish with one final top coat.
Q: Is PU moulding safe for indoor air quality?
A: Yes. Premium PU mouldings are manufactured without formaldehyde, asbestos, or VOCs. They meet EN 13501-1 Class E fire classification as a minimum, with Class B fire-retardant versions available for commercial projects. The factory-applied water-based primer further reduces off-gassing once installed.
